Harold & Kumar 3 began filming today in a mall in Michigan, and the cast and creators are tweeting about their adventures. John Cho, the Asian in the dynamic cannabis-loving duo had this to say: "In Michigan, @pattonoswalt in my vicinity, holding a sketch pad, duct tape, and a reel to reel audio recorder. Eeesh." Whoa, so Patton Oswalt is on set too?! Oswalt tweeted: "Maybe it's this Michigan air, but @JohnTheCho is looking huggable, chloroform-able, and bury-able."As much as I'd love Oswalt being there to star in the movie, I gather by his tweet that he's simply hanging around set to chloroform, rape, and murder John Cho. He didn't specifically say "rape" but chloroform isn't used for much else these days. And since Kal Penn didn't chime in on Twitter, he must already be under floorboards somewhere. Check out some pics from the set after the jump…

Their recent strokes have only made them funnier. Harlold & Kumar creators Hayden Schlossberg and Jon Kurwitz are moving from hamburgers to baked goods. The duo is mounting American Pie 4 as both writers and directors. That leaves directing duties on A Very Harold & Kumar Christmas to newcomer Todd Strauss Schulson.The story for the latest Pie sequel is being kept under wraps, though I'm sure embarrassment, bizarre sexual fetishes, and Jim's Dad will remain major components. None of the original cast has officially signed on yet, but extreme interest has been voiced. You don't say? Should I go with a Jason Biggs, Chris Klein, Thomas Ian Nicholas, Tara Reid, Shannon Elizabeth, or Natasha Lyonne joke here… You know what, I'm gonna let it be. I'm sure the fact that the band camp girl is more prosperous than any of them is shameful enough. (THR)
